High Pressure Resistance Large Diameter Carbon Fiber Tube Manufacturer

A composite tube is manufactured from two or more constituent materials. Individually, these materials have significantly distinctive properties. These properties could be either physical or chemical, and when these materials have been combined by the Composite Tubes manufacturer, the result is a composite material with characteristics unconventional to that of either of the individual components. The preference for composites comes down to several reasons. It could be their lower cost, higher strength, or even their lighter weight. One of the most primary applications for a Composite Tube is its use in structural purposes for buildings, bridges, and construction.

Carbon fiber tubes are ideal for both hobbyists and industry professionals. Using the rigidity of the carbon fibers, an extremely stiff yet lightweight tubular structure can be used in a wide range of applications.

Carbon fiber tubes can replace steel, but more often than not, it is replacing aluminum. In many instances, a carbon fiber tube can weigh 1/3rd of an aluminum tube and still have the same or better strength characteristics. Because of this, carbon fiber reinforced tubes are often found in applications lightweight is crucial, like aerospace, race cars, and recreational sports.

Carbon Fiber Tube Applications

Any application where weight is crucial, switching to carbon fiber will be beneficial. The following are some of the most common uses of carbon fiber tubes:

• Aerospace beams and spars
• Formula 1 structural components
• Arrow shafts
• Bicycle tubes
• Kayak paddles

Manufacturing Carbon Fiber Tubes

LIJIN composite structures can be difficult to manufacture. This is because pressure needs to be applied to both in internal and the external side of the laminate. More often than not, carbon fiber tubes with a continuous profile are manufactured by either pultrusion or filament winding.

Pultruded tubes are by far the most cost-effective method of manufacturing continuous composite profiles. When pultruding a hollow tube, a "floating mandrel" is required. A chromed steel rod is firmly affixed in place on the side of the die where the raw material enters. The mounting hardware is far enough away that does not interfere with the impregnated fiber as it enters the die.

The space between the mandrel and the die will determine the wall thickness of the carbon fiber tube.

Pultruding carbon fiber tubes allow for the production of tubing of virtually any length. Transportation of the tube is generally the restriction on length. In pultrusion, most of the fiber will run the direction of the tube. This creates a tube with a tremendous about of stiffness, but not much hoop strength, or cross-directional strength.

Shanghai Lijin focuses on the Carbon Fiber industry and offers carbon fiber tubes, plates, and aluminum CNC services.

Being experienced in the carbon fiber applications for over 7 years, Shanghai Lijin manages customized production according to various industry standards. Shanghai Lijin started to keep in stock for some standard

sized and frequently ordered tubes and plates. This enables Shanghai Lijin to make prompt delivery. Not only

can Shanghai Lijin complete mass production orders in short period, we can even ship normal sample, prototype orders of Carbon Fiber Plate CNC parts in just SEVEN days after order confirmation when the

drawings are available. Shanghai Lijin is dedicated to solve any technical points during the production and new item developing to ensure the quality.

Carbon Fiber tube production is Shanghai Lijin’s core business and occupies 70% of our turnover.
The carbon fiber tubes Shanghai Lijin mainly produce is table-rolled and oven thermoset. The tubes can be Full Carbon or Carbon Fiber and Fiberglass composite, depending on the application, weight limit,mechanical

strength and surface requirement.Shanghai Lijin offers top quality ROUND carbon fiber tubes. The general OD tolerance we achieve is +/-0.10mm and it can be even +/-0.05mm after our special surface process.

The maximum length of the tube can be 5500mm.

Besides the traditional table-rolled carbon fiber tubes, Shanghai Lijin also offers REAL Filament wound carbon fiber tubes,which are widely used for mechanical strength like auto driving shaft, antennas, even for military

applications. The filament wound carbon tubes are wound at a certain angle like 30 or 45 degree. We invested the new production line from Jun 2013 and this increases Shanghai Lijin’s advantage in the carbon

fiber tube industry. There are just a few real filament wound carbon fiber tube manufacturers in domestic

China and we are one of them.
 

Since the rapid growth of UAV in the international market, instead of the standard plane like Phantom from DJI, RC fans are getting more interested in the customized multicopters. As carbon fiber is the most preferred

material for UAV, Carbon Fiber CNC parts demand is increasing. Shanghai Lijin sticks to offering OEM service for the international market, fine quality and prompt delivery.To ensure the thickness tolerance +/-0.10mm and minimum warp of the Carbon Fiber plates that are used for the cutting, Shanghai lijin execute high standard to

the plate production. For the normal thicknesses including 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm,
Shanghai Lijin keeps regular stock, to make sure the raw material will be available for cutting immediately when order is firmed.Experienced engineers are in Shanghai Lijin’s office ready to deal with different types of

drawings from customers. No matter the drawing formats are .DWG, .DXF that can be edited by AutoCAD

and used directly for production, 3D drawings like .IGS, or even draft drawings, our staff can do adjustment and change to customer’s idea. Our engineers are also good at English communication, Email and IM is easy

for them. Editing drawings for customers is FREE* of charge. Shanghai Lijin is having several professional CNC machines for carbon fiber cutting and drilling, with the capacity of cutting 20-50pcs standard full sized plate per day. The carbon fiber chassis general cutting tolerance Shanghai Lijin offer is +/-0.02mm. The

special designed cutting solution ensures the smoothness of the cutting edge.

‘Customers’ Persuit for Change, Lijin’s Motivation for Growth’, Shanghai Lijin takes customers’ demand for center, enhances the
customer satisfaction, and grows with customer.
